CHELSEA boss Jose Mourinho was in a curt mood on the eve of his team’s Champions League semi-final first leg with Atletico Madrid and refused to discuss Saturday’s controversial Premier League loss to Sunderland.

The relegation-threatened Black Cats won 2-1 at Stamford Bridge to end Mourinho’s 77-match unbeaten home record in the Premier League and further dent Chelsea’s title hopes, leaving the old European Cup as their most likely chance of silverware this term.

Midfielder Ramires, Mourinho and his assistant Rui Faria could all face scrutiny when the Football Association returns today from its extended weekend for incidents during the loss.

Mourinho made only a statement after the match in which he made veiled criticisms of the officials and referees’ chief Mike Riley, and he declined to elaborate yesterday.

‘‘Today and tomorrow and also Wednesday are Champions League days and if you want to speak about the Premier League you have 19 teams in England that you can speak with,’’ Mourinho said.

‘‘Chelsea today and tomorrow is Champions League and we are only available to speak about Champions League.

‘‘We are lucky to be involved in the Champions League, so we are lucky that in the next two days we don’t think about the Premier League and what’s happened and what is going to happen because now we only think about tomorrow.’’ Asked how important it is that his players, his staff and he himself keep their composure in the Vicente Calderon Stadium this evening, Mourinho added: ‘‘We always behave in relation to the situation.’’ Ramires’ domestic season could be at a premature end after he caught Sebastian Larsson with a failing arm, while Faria was sent to the stands for angrily approaching fourth official Phil Dowd.

Curiously, Chelsea face their own goalkeeper tonight as Thibaut Courtois is poised to feature against his parent club during his third successive season on loan at Atletico.

It was reported that Chelsea would demand the Spanish side pay a fee of around 3million euros for each game in accordance with their confidential loan agreement, but UEFA announced it expected Courtois to be free to face the Blues.

Mourinho said: ‘‘I think that on UEFA decisions it’s better not to comment, you just accept or if you don’t accept you don’t make any comment.

UEFA decides and I think managers don’t comment.’’
